Family-Based Intervention with High-Risk Infants and Their Families

A model of family-based intervention for high-risk infants hospitalized in the neonatal intensive care unit and their families is presented. The theoretical underpinnings, principles, and nature of the intervention are described. The adaptation of the model from a clinical–research demonstration project to a clinical consultation service is highlighted, with particular emphasis on the practical application of the model. Domains of the intervention include infant behavior, family organization and functioning, caregiving environment, and home discharge/community resources. Three case illustrations are provided to demonstrate the breadth of the intervention and how it can be individualized based upon the presentation of the infant and family.     

Effects of serial versus concurrent task sequencing an acquisition, maintenance, and generalization

Effects of serial and concurrent task presentation on skill acquisition, generalization, and maintenance were compared. Two severely retarded females participated. During serial training, items of one response class, tracing, were trained to mastery before those of a second task, vocal imitation. In the concurrent method, training on two different tasks, tracing and vocal imitation, alternated within sessions for fixed periods of time. There were no major differences between the serial and concurrent methods of instruction in the number of steps attained per behavior or in the number of trials required to reach criterion levels of performance. It was found however, that concurrent training resulted in more generalization. Retention results were not consistently related to training method.     

THE EFFECT OF EXPERIMENTER FACIAL ORIENTATION DURING IMITATION MAINTENANCE1

The training and maintenance of imitative responding has become an important therapeutic process with language-handicapped children, as indicated by Garcia and DeHaven (American Journal of Mental Deficiency, 1974, 79 , 169–178). Typically a training “package” is used, that might entail the use of operant shaping, fading, reinforcement, and punishment techniques designed to increase correct imitation and decrease incorrect responding. Only recently have studies begun to concentrate on the components of these training “packages”. Steinman (Journal of Applied Behavior Analysis, 1970, 3 , 159–167) highlighted the roles played by less conspicuous but functionally important components of these packages. The present study attempted to provide a systematic extension of this work within an applied context. Using subjects who were responding at high levels during an imitation-maintenance procedure, experimenter facial orientation (experimenter's eyes and head oriented towards the subject's face and head), was systematically manipulated for experimentally determined “types” of imitative behavior. Differential responding within these parameters provided an evaluation of facial orientation as a functional component within this training package. Three retarded children participated in the study. Two types of topographically different imitative responses were defined for experimental purposes (“standing” and “sitting”). Each subject progressed through four conditions of the study, which called for the reinforcement of all imitative responses. But during preselected conditions, experimenter facial orientation was removed from the therapeutic package for one of the two topographical types of imitation. Results indicated that imitation of the two topographical types of models was dependent on the presence of experimenter facial orientation within the experimental procedure.     

Transient effects of acquisition history on generalization in a matching-to-sample task

This study examined the role of learning history on the acquisition of a matching-to-sample task. Twelve preschool children learned four stimulus classes through instructions, shaping, or imitation. After reaching criterion, the subjects were exposed to changed discrimination contingencies to determine how each learning history affected the acquisition of responses appropriate to the new contingencies. All subjects reached criterion on the new relations, although the subjects with a shaping history adapted slightly more quickly than those subjects with a history of instructions or imitation. Given sufficient exposure to changed contingencies, rule-driven insensitivity to contingencies was overcome by experience with consequences. This result may be specific to younger subjects, but it suggests that instructions can be used in education without creating insensitivity to contingencies.

Individual differences in neonatal “imitation” fail to predict early social cognitive behaviour

The influential hypothesis that humans imitate from birth – and that this capacity is foundational to social cognition – is currently being challenged from several angles. Most prominently, the largest and most comprehensive longitudinal study of neonatal imitation to date failed to find evidence that neonates copied any of nine actions at any of four time points (Oostenbroek et al., [2016] Current Biology, 26, 1334–1338). The authors of an alternative and statistically liberal post‐hoc analysis of these same data (Meltzoff et al., [2017] Developmental Science, 21, e12609), however, concluded that the infants actually did imitate one of the nine actions: tongue protrusion. In line with the original intentions of this longitudinal study, we here report on whether individual differences in neonatal “imitation” predict later‐developing social cognitive behaviours. We measured a variety of social cognitive behaviours in a subset of the original sample of infants (N = 71) during the first 18 months: object‐directed imitation, joint attention, synchronous imitation and mirror self‐recognition. Results show that, even using the liberal operationalization, individual scores for neonatal “imitation” of tongue protrusion failed to predict any of the later‐developing social cognitive behaviours. The average Spearman correlation was close to zero, mean r_s = 0.027, 95% CI [?0.020, 0.075], with all Bonferroni adjusted p values > .999. These results run counter to Meltzoff et al.'s rebuttal, and to the existence of a “like me” mechanism in neonates that is foundational to human social cognition.     

The ontogeny of cumulative culture: Individual toddlers vary in faithful imitation and goal emulation

The success of human culture depends on early emerging mechanisms of social learning, which include the ability to acquire opaque cultural knowledge through faithful imitation, as well as the ability to advance culture through flexible discovery of new means to goal attainment. This study explores whether this mixture of faithful imitation and goal emulation is based in part on individual differences which emerge early in ontogeny. Experimental measurements and parental reports were collected for a group of 2‐year‐old children (N = 48, age = 23–32 months) on their imitative behavior as well as other aspects of cognitive and social development. Results revealed individual differences in children's imitative behavior across trials and tasks which were best characterized by a model that included two behavioral routines; one corresponding to faithful imitation, and one to goal emulation. Moreover, individual differences in faithful imitation and goal emulation were correlated with individual differences in theory of mind, prosocial behavior, and temperament. These findings were discussed in terms of their implications for understanding the mechanisms of social learning, ontogeny of cumulative culture, and the benefit of analyzing individual differences for developmental experiments.     

Quintilian and the Pedagogy of Argument

Originating in the Sophistic pedagogy of Protagoras and reflecting the sceptical practice of the New Academy, Quintilian's rhetorical pedagogy places a special emphasis on the juxtaposition of multiple, competing claims. This inherently dialogical approach to argumentation is referred to here as controversia and is on full display in Quintilian's own argumentative practice. More important to this paper, however, is the role of controversia as an organizing principle for Quintilian's rhetorical curriculum. In particular, Quintilian introduces the protocols of controversia through a series of progressively more complex exercises in imitation, role-playing, and declamation (now referred to as situational games). All of these exercises are open for adaptation by contemporary teachers who would promote a dialogical approach to argument, i.e. argument with its methods of inquiry, invention, and judgment based on direct interaction with opposing parties.     

Cognitive imitation in typically-developing 3- and 4-year olds and individuals with autism

Individuals diagnosed with autism suffer from numerous social, affective and linguistic impairments. It has also been suggested that they have a global imitation deficit. That hypothesis, however, is compromised by the fact that individuals with autism suffer from various motor impairments. Here we describe an experiment on cognitive imitation, a type of imitation that doesn’t require motor learning. Nine male autistic subjects and 20 typically-developing 3- and 4-year olds were trained to respond, in a prescribed order, to different lists of photographs that were displayed simultaneously on a touch-sensitive monitor. Because the position of the photographs varied randomly from trial to trial, sequences could not be learned by motor imitation. In three different imitation treatments, including a ghost control, autistic subjects learned new sequences more rapidly after observing a model execute those sequences than when they had to learn new sequences entirely by trial and error. Moreover, the performance of autistic subjects did not significantly differ from the performance of typically-developing controls. The result of this and other studies suggests that individuals with autism suffer from a specific novel motor imitation deficit.
